. l To all persons to whom these prese-nts may come:

Be it known that I, LoUIs GoDDU, a citizen of the Dominion of Canada,but temporarily residing at Boston, of the county of Suffolk and Stateof Massachusetts, have made a new and useful Invention or Improvementsin Machinery for N ailing Shoe-Soles or variousother articles with wire;and do hereby declare the same to be fully described in the followingspeciiication and represented in the 'accompalnying drawing, of which-`a nail-driver and its operative mechanism, a

mechanism for feeding in the wire from which each nail is to be severed,a mechanism for receiving the wire and transferring the nail portionthereof to the guide-nose passage, and,

finally, a mechanism for severing a nail from the wire. a

The special object for which the present machine is designed is thefixing of soles or welts in place by a few nails preparatory to theirbeing regularly pegged or nailed to the upper of the shoe; an attendantpresenting, as may be required, the lasted shoe to the nose-piece of themachine, and at the same time operating the pedal of the machine by hisfoot, so as' to put the machine in operation and cause it to drive anail through such part of the sole or welt and into the last where itmay be desir able to have Vone inserted. My present iinprovements may besaid to consist as follows, viz.: In certain mechanism, as hereinafterdescribed, for regulating the feeding forward of the wire; alsomechanism for actuating the main shaft of. the machine and holding it atrest under circumstances as hereinafter explained.

A denotes the stock, head, or frame for sup porting the operative parts,it terminating in or being provided with the guide-nose B, which Y eachdownward movement of the pedal.

has a vertical passage, a, leading down through it. Through this passagethe nail, after being severed from the wire, is driven or forced by thenail-driver, shown at c. The said naildriver is fixed in the lower partof a carrier or vertical slide-rod, C, arranged in the frame or stock A,and provided with a spring, D; the purpose of which is to depress thecarrier after each elevation of it, such depression being with powersufficient to cause the nail-driver to force the nail into the articleinto which it may be required to be driven. Within the frame or stock A,and disposed therein, `as represented, is the main shaft E, carrying apinion, F. This pinion Vengages with a gear, d, arranged on a stationaryarbor, e. fixed to the gear d, on one side'oi it, a ratchetwheel, f,(see Fig. 4, which is a side view of the ratchet and geen) with which adraw-pawl, g, applied to one side of a wheel, It, and provided with anactuatingspring, s, operates. The

wheel It turns freely on the said arbor, and

while in operation is to have a reciprocating rotary motion, such beingto be effected by a pedal connected with the wheel by a rod, fi, pivotedto the two, a spring being used to elevate the pedal and rod. An entirerevolution is to be imparted to the shaft E during A cam-wheel, lc,shown in side view in Fig. 5, receives in its cam-groove l afriction-rollerprojectin g from one side of an arm, m, such arm beingextended upward from a shaft, n, to whose front end the transferrer'L isiixed, the latter deriving' its motions from the said shaft,

arms, and cam. Furthermore, there is iixed on the shaft E, at its frontend, a cani or wiper, 0, whose purpose is to effect the elevation of thenail-driver carrier C at the proper times and to allow it to be drivendownward by the spring D. The wire from which the nails are to besuccessively cnt is to be led through a passage, w, of a guide, I, andthence against the milled or toothed periphery of a feedfwheel,Kg-thence through a conduit, o, to and past the cutting-edge ofthestationary cutter m, arranged as shown. From thence the wire passes intothe passage z of the transferrer L. The

said transferrer carries a cutter, y, which, op` eratin g in conjunctionwith the stationary cutter w, serves, at the proper. period, to sever aThere is nail from the wire. By the movements of the transferrer L thewire will be cnt or the nail will be severed from it by the cutters, andsubsequentlywill be moved directly over the guidenose passage a, readyfor being driven by the nail driver. There is applied to the peripheryof the cam-wheel 7c a friction-brake or presser, a2, which, arranged inthe frame, as shown, has a spring, b2, for forcing it downward, theelastic force or pressure of the spring being increased or diminished bya screw, c2,l screwed into the frame or head A and against the up# perend of the spring. Thisfrictiorrbrake is to prevent the cam-wheel frombeing revolved by its momentum beyond what may be necessaryV for itssuccessful' action. The brake a2 is also to hold the shaft E fromrevolving while the pawl-carryingwheel his being moved backward so as toslip thepawl g over the ratchetwheel'j'. The feed-wheel K revolves on anarbor, 7d, projecting from the head A. A ratchet or pawl, l', carried byan arm, m', and arranged with the toothed periphery of the feed-wheel,in manner as shown, operates such wheel. The arm m projects from ashaft, n', which extends through the arbor k. From the rear end of suchshaft n an arm, of, is` extended, and carries a friction-wheel, p', toact against the periphery of a cam, q', fixed on the outer side of thecam-wheel 7c, the shape of the cam q being shown in Fig. 6. There isconnected to the arm o a spring, 1", which is fastened to a projection,s1, from the frame or head A, all being arranged as' shown. This springdraws the friction-roller closely upto the cam. Fig. 7 is a horizontalsection taken through the axis of the shaft n and the parts adjacent andin the vicinity of such sha-f t. There projects back from the frame A,and concentric with the shaft n4, a tubular arbor, tf, which constitutesthe fnlcrnm of a stop-lever, It, a top view of such lever being given inFig. 8 and a side view of vit in Fig. 9. From the shorter arm u of suchlever a stud, c', is extended against the inner edge of the arm o. Thearm w of the stop-lever R is hollow or chambered to receive a spring,m', which is held in place inthe arm by a screw, y', screwed therein andagainst the outer end of the spring. the spring bears against the arbort. From thesaid lever an arm, z', extends, in manner as shown, betweenthe inner ends of two screws or adjustable stops, a3 b3, arranged in theframe A, in manner as represented. The purpose o'f the stop-lever R andits adjustable stops c3 b3 is to regulate the extent of movement of thearm o toward'the cam q', and, as a consequence, the feeding of the `wirein order to cause the nail cut off and driven to have any desirablelength.

By taking hold of the arm fw ofthe lever R an attendant will be`able tomove the stop-lever between its stopsA more or less, as may be Ylrequisite, to vary the feed of the wire, the

spring of the lever-sufficing to hold, by friction, the lever in theposition in which it may be so placed.

In the above-described machine, whatIclaiin as my invention may bestated as followsthat is to say:

I claim the combination and arrangement of the stop-lever It, theadjustable stops a3 b3, the feed-wheel K, the pawl l1, the arm m', theshaft nf, the arm o", the spring r', the roller p,and the camfq, allbeing constructed and applied together, substantially in manner and tooperate as described. j

Also, the combination therewith of the spring x', or such, and the adjListing-screw y', arranged in the stop-lever, as set forth.

Also, the friction-brake c2 and its spring b2 and screws c2, incombination with the gea-rs F d, ratchet-wheel j', and reciprocatingpawl g and its carrier It applied to the shaft E, and with the cam-wheelk of the mechanisms, as described, for operating the transferrer andfeed-wheel. Y
